I have a 1975 40-ph Johnson outboard motor I have ran the motor on pennzoil two cycle oil ever since I've had the boat. Today I couldn't find any pennzoil so I bought quakerstate two cycle oil. I filled the tank with 3 gallons of gas and poured the recommended amount of oil into the can. So know I have 3 gallons with pennzoil and 3 gallons with quakerstate. My motor stopped running while I was out on the lake and won't restart. I had to use the trolling motor for a 1/2 Mille into the wind to get back. Glad the battery didn't die. Now my question is would that have messed my motor up using two different oils?

Re: Mixing oil

I had a '75 Johnson at one point. Pretty good reliable motor. I would check to see if the plugs are fouled or if the stator went bad on it. That's what happened to mine. They usually go bad without warning.

Hope this helps brother

Re: Mixing oil

When you say 'stopped running', did it quit running, or did it sieze? As long as both oils were TC-W3 mixed at 50:1 they weren't the problem
